EVERFRESH
®
WATER CARE SYSTEM
The everFresh water care system is comprised of the following products:
• Clean-Screen
®
Pre-Filter
• Sodium dichlor
• Monopersulfate (MPS)
• FreshWater
®
III high output ozone system
• FreshWater
Ag+
®
silver ion purifier
Clean-Screen pre-Filter
is used when filling a spa for the first time or at refill. It attaches to a garden hose and filters out rust, dirt, detergents, algae
and chemicals.
Sodium Dichlor (chlorine)
is the only recommended sanitizer that will work in conjunction with all of the other products in this system.
FreshWater III high output ozone system
uses corona discharge technology to produce a high concentration of ozone which is injected into the spa
water.
monopersulfate (mpS) i
s an oxidizing chemical used to prevent the buildup of contaminants, maximize sanitizer efficiency, minimize combined
chlorine, and improve water clarity.
FreshWater
ag+
silver ion purifier
introduces silver ions into the spa water, inhibiting bacteria growth. When combined with MPs, or chlorine,
oxidizes particulates in the spa water.
It is important to follow the recommended application and maintenance programs outlined for each product’s use.
If the spa is being used over an extended period of time, such as a whole afternoon or evening, additional sanitizer will be needed.
A weekly “shock treatment” is required.
The shock treatment quickly destroys any remaining contaminants while revitalizing the silver ion cartridge, allowing the silver ions to continue to be
released into the water. Without this weekly shock treatment, the silver ion cartridge may stop releasing silver ions into the water.
To weekly “shock treat” your spa you may use either MPs or sodium dichlor. It will require much less sodium dichlor to administer the shock
treatment than MPs (one teaspoon of sodium dichlor has oxidizing capabilities comparable to two tablespoons of MPs). sodium dichlor may be a
more appropriate weekly shock for those users that experience heavy bather load conditions.
ImpORTaNT NOTE:
MPs is an oxidizer, not a sanitizer.
